Extended thread_create, but how do I make sure it applies to specified styles?

I have extended thread_create that enters in special information into our database. That information is requested only when a user is creating a thread in a specific set of node/forums that I have applied a specific style to.

Almost like asking and entering in specific information about your collectable toy when you're creating a new thread in a node dedicated to a specific collectible toy. It won't ask for the information in any other forum/node since the style is only applied to this forum/node.

However, at the moment, when a user hits "submit", it submits to the database regardless of what node/forum we're in.

Is there a way for me to only allow these database entries when a user is creating a thread in a specific forum/node?

Any help would be appreciated. Sorry if I haven't been clear, let me know!
